Behaviour of clock up / clock down
If there is no need for processor-performance, the processor will clock down automatically, the same way the processor should clock up, if you start a processing intensive process.
The processor doesn't clock up!
There are serveral causes:
- Windows displays a wrong freq. (often on Athlon64 or Turion64).
Answer: Use special tools for checking, e.g. CPU-Z (core speed) - AMD-processors:
Download processor drivers (Athlon 64, Turion 64, Mobile Sempron) - The notebook use rechargeable battery
You should change the "power options properties->power scheme" to e.g. "Home/Office Desk" - Load BIOS defaults
Eventually you have to load the "Optimized defaults" in the BIOS, so that the automatically changing of core-speed works. - There is a option in the BIOS, which prevent clocking up.
- If all of this doesn't work and if it is a Pentium M (Centrino):
Eventually SpeedStep is deaktivated. Either you try to activate it by updating your BIOS or you activate it with RMClock.
